According to the Boston Globe, which is shadowing him diligently, President Obama is keeping a pretty low profile during his Martha's Vineyard family vacation. He did go to a bookstore on Friday, where he bought Isabel Wilkerson's powerful history of black migration, "The Warmth of Other Suns," to read (you can read the Strib review here), as well as a handful of novels.

But it was his daughters' choice of books that got hearts a-fluttering on Washington Avenue in Minneapolis. Sasha and Malia chose "My Green Manifesto: Down the Charles River in Search of the New Environmentalism," published by Milkweed Editions.

"My Green Manifesto" by David Gessner, was one of five titles recommended to Obama by the Boston Globe in an earlier column. There's no word on whether or not that influenced his daughters' choice, but I'd like to assume it did. I'd like to assume that intelligent and literate teenagers are reading newspapers and responding to what they read, and that the art of book reviewing remains relevant. Wouldn't you?
